Denmark attended Florida Agricultural and Mechanical University (FAMU) in Tallahassee, Florida on a sports scholarship. While pursuing a Bachelor of Fine Art degree, Denmark came under the tutelage of Dr. Samella Lewis, who exposed him to the great traditions and accomplishments of the African-American art movement. After graduating, Denmark moved to Brooklyn, New York, and began a career as an art teacher in the public school system. He later earned his MFA at Pratt Institute of Fine Art, New York. During this time he was exposed to abstract expressionists including Norman Lewis. Romare Bearden, Jacob Lawrence and Ernest Crichlow were also influences who instilled an appreciation for his African heritage. He began experimenting with collage, watercolor and charcoal but found he was drawn to the improvisational aspects of collage. His work has been exhibited internationally and can be found in the collection of the Metropolitan Museum of Art, New York, among others.
